Carl,
I used a card-board like gasket material sold in any automotive supply
store, and used suitably sized templates to cut out my gasket with a very
sharp knife. I put a piece of the material in a jar with auto-gas , while I
was still working on the plane. It never reacted to the gas in any way and
it is still the same gasket six years later.
My gascolator is mounted on a small quarter bulkhead low down behind the
trailing edge of the left flap. The fuel-line goes from the selector valve
to the gascolator, then forward through the electric boost-pump , which is
mounted forward on the same bulkhead, through the tunnel and firewall to the
mechanical pump. I put an inspection door under the gascolator for testing
and servicing. It works very well.
Hope this explains it.
Peter Timm
